In the case of organic pollutants, such as pesticides, explosives and industrial chemicals, certain plants may render these substances non-toxic by their metabolism.
inorganic Describes material that is of mineral origin. Specifically, describes chemical compounds that do not contain carbon and hydrogen. Compare organic.
VOCs or "volatile organic compounds" VOCs are primarily the lighter 'fractions' of oil or hydrocarbons (i.e., the parts that evaporate easily because they have a low boiling point).
